Abstract

The writer was confronted with the problem of measuring the temperature of a tungsten wire enclosed in an evacuated tube. A thermocouple could not be used because it would be certain to apply unknown torques to the wire and also to disturb the temperature distribution along the wire. An optical or radiation method of temperature measurement would overcome both of these difficulties. An optical pyrometer suitable for accurate temperature determinations and flexible enough to be of general use in a physical laboratory is not on the market at the present time. This led the writer to the task of designing and constructing the instrument described in this article. For the benefit of those who are not familiar with optical pyrometry a brief sketch of the theory and design of a Holborn-Kurlbaum optical pyrometer has been included.
